Are you looking to become a dental assistant or are moving as a current dental assistant? Make sure to check the dental assistant requirements in New Mexico to see if you are still qualified in the state to practice.

Each state has different requirements for dental assistants, here are the levels, and functions permitted for dental assistants in New Mexico.

Levels of Dental Assistants in New Mexico

There are three levels of dental assistants in NM:

  1. Dental Assistant

2. Dental Assistant with State Certification in Expanded Functions

To perform expanded functions under the general supervision of a licensed dentist in New Mexico, a dental assistant must earn state certification in each of the desired expanded functions. To qualify, one must do the following for each of the expanded functions:

Note: Holding a current DANB Certified Dental Assistant (CDA) certification automatically qualifies a dental assistant to apply for state certification for each of these expanded functions.

A dental assistant who is certified to perform dental radiography, coronal polishing, pit and fissure sealants, and/or topical fluoride procedures in another state with requirements not less stringent than those in New Mexico may apply for state certification based on credentials (see New Mexico Rules and Regulations, section 16.5.33.13 for details).
